Actually, I’m referring to the Gemara in Eiruvin 13b (and Brachos 64)

Translation: Whoever tries to push his luck (lit. hour), his luck will push him. Whoever accepts his fate, fate will stand him well.
I know that the whole issue of Mazal is confusing to some/many, and unliked by even more. It is something that has to be properly understood, with its appropriate context. Rashi explains this Gemara that when you notice that times aren’t good you shouldn’t press it. Don’t keep on investing more and more.
Of course, it doesn’t mean that you should give up. Also, how do you know when your Mazal switched? However, I think that the OP had a good understanding of how to apply this, being that it was a personal observation.
I think the OP was about how to behave more than what to believe, so we’ll try not to discuss Bitachon & Hishtadlus (as much as there is to discuss).
